CAL-Fire and Gridley-Biggs Police Officers were called to 100 Kentucky Street, the location of Mary's Gone Crackers Thursday, February 28, 2013 at 7:02 p.m., for the report of an explosion.

Sutter County Fire also responded to the call.

An explosion in an oven caused one moderate injury to a 27-year-old male who was airlifted to Enloe Medical Center. The male adult was said to be coherent and able to speak with first responders.

The second injury was to a female employee who had minor injuries and was transported to Biggs-Gridley Memorial Hospital.

Other employees were checked by medical responders but did not require hospitalization.

Part of the factory was evacuated by firemen and some returned to work by 8 p.m., while others left the premises.

Estimated damage was listed by CAL-Fire as $10,000.

Cal-Osha is investigating the cause of the explosion that did not cause any smoke or fire.

Mary's Gone Crackers was recently in the news when Federal agents raided the facility on January 31, 2013 for illegal employees working there.

Investigators estimated that at least 49 of the 159 employees could not show proper documentation during an audit held March 2012. Investigators believed all 49 social security numbers provided by the business were fraudulent.

Immigration officers were told last May that 48 of the 49 employees no longer worked at the facility but officials stated they believed that 13 supervisors were fired and rehired a week later, with the business giving all 13 assumed names to conceal their identities from government officials, the warrant stated.
